This entire premise is nonsensical. I'm almost be amused by the fact that the article states that all you need to determine the identify of an element is to look at its name and scope in the document. > > http://aspn.activestate.com/ASPN/Mail/Message/xml-dev/1654227 > ["Oh, there is one way to stay sane and still use namespaces. > Get all your > tools from end to end from a single vendor."] In his experience namespaces have caused more problems than they've fixed. In my experience they haven't. Of course, everyone can dish out anecdotal tales of how Technology X or Technology Y was a poor fit in a particular instance. After all, didn't McKinsey just publish something similar on "The Truth About XML" at http://news.com.com/2030-1085_3-1025872.html > http://www.itworld.com/nl/xml_prac/04112002/ The core point here is that XML namespaces makes XML technologies more complex than if they just supported XML 1.0. Agreed. XML technologies would also be easier if they didn't support the more esoteric aspects of XML 1.0 as well (parameterized entities, CDATA sections, DTDs, PIs, etc). This doesn't these features are not beneficial. > http://aspn.activestate.com/ASPN/Mail/Message/xml-dev/1656220 Another all you need is an element's position in the document to uniquely identify it post. So all I need is an element's position to uniquely identify it in an XSLT stylesheet or a WordML document? This argument works in the simplest of cases or when you have a priori knowledge of all the data that will be in your document. -- PITHY WORDS OF WISDOM Any given program, when running, is obsolete.
